There is one definite advantage of the long dark nights at this time of year. It is that you can see morning satellite flares without getting up early compared to the Summer months. But what are Satellite flares? These are spectacular flashes in the night sky that last a few seconds. They are caused by sunlight being reflected off the surfaces of satellites on to small sections of the earth’s surface. They can be predicted accurately for any given spot on the planet. They usually occur just before dawn and after dusk when the surface below is in darkness, but when the satellites above can still reflect the suns rays. The occurrences vary in brightness, but some can reach a startling brightness of -8 which is brighter than the planet Venus.
